Surfboard having maneuvering structure and pressure dispersion plate

ABSTRACT

A surfboard includes a board member for supporting a user and having two depressions formed in the rear portion and the upper portion of the board member and inclined rearwardly from a front end toward a rear end, and having a swelling formed between the depressions of the board member, and a performance enhancing device is formed in an outer side portion of each of the depressions of the board member for enhancing performance and higher directional control, increasing power when exiting a turn and the ability to hold its place higher upon the wave face, reducing sideslip, thereby allowing the board member to be effectively maneuvered or controlled by the user.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a surfboard, and more particularly to a surfboard including a method of optimising control of direction and speed, and enhancing the performance of the surfboard.

The surfboard does this by:

controlling the angle and direction of the board in relation to the waves,

considerably reducing or preventing sideslip,

increasing the speed of exiting turns,

allowing the rider to surf/drive higher along the wave face thereby enabling the rider to take advantage of smaller waves than is otherwise possible,

further it incorporates a device to strengthen the board at its normally weakest point.

2. Description of the Prior Art

Typical surfboards comprise a planar board body made of rubber, plastic, foam, or other synthetic materials of a light weight for being floated on the water and for carrying the user thereon while surfing.

However normally, the under surface of the board body has a planar surface or only small, smooth rounded channels, with limited directional control.

Further, in conventional boards the continual pressure of the rider's elbows on the peripheral edges slightly forward of the midpoint cause compression and thinning of the board. This results in weakness of the board and high potential for the board to snap in two along a line between the two elbow pressure points.

The present invention has arisen to improve on the performance and strength of conventional surfboards.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a stronger construction of the surfboard and including a device for allowing the surfboard to be more easily maneuvered and steered by the user, with greater performance while surfing.

In accordance with one aspect of the invention, there is provided a surfboard comprising a board member for supporting a user and including a front portion and a rear portion, an upper portion and a lower portion, and including two depressions formed in the rear portion and the under portion of the board member and inclined rearwardly from the front end to the rear end of the depressions of the board member, and including a swelling formed between the depressions of the board member, and including a performance and directional device formed in the outer side portion of each of the depressions of the board member for enhanced performance and directional control while surfing on waves.

The swelling includes a lower portion flush with the under portion of the board member, and includes a wider front portion and a narrower rear portion.

The swelling includes two curved side portions. The directional devices are downward faces formed in the outer side portions of the depressions of the board member.

The board member contains a pressure-dispersion plate located the body of the board between the upper surface and the lower surface and within the peripheral edge, slightly forward of the midpoint of the board member.

The pressure-dispersion plate acts as a load-spreading device to reduce the compression depth and construction damage to reduce compression of the board and structural damage caused by the elbows of the rider 80 thereby preventing deformation of the board and allowing it to retain its original rigidity, thickness and strength.

Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and initially to FIGS. 1-3, a surfboard 1 in accordance with the present invention comprises a board body or board member 10 for supporting a user 80 (FIG. 4) and including a front portion 11 and a rear portion 12, and including an upper portion 14 and a bottom or lower portion 13, and including two depressions 15, 16 formed in the rear portion 12 and in the lower portion 13 thereof and inclined rearwardly from the intermediate portion of the board member 10 or from one end or the front end 17 of the depressions 15, 16 toward the other end or the rear end 18 of the depressions 15, 16, or the rear portion 12 of the board member 10, and including a rib or swelling 19 relatively formed or defined between the depressions 15, 16 of the board member 10.

It is preferable that the depressions 15, 16 of the board member 10 include a narrower front portion or front end 17 and a wider rear end 18 for suitably enhancing performance and higher directional control, increased power when exiting a turn and the ability to hold its place higher upon the wave face, reducing sideslip.

The swelling 19 includes an under portion or lower surface flush with the lower portion 13 of the board member 10, and includes a wider front portion 20 and a narrower rear portion 21, and includes two rounded or curved side surfaces or side portions 22 for enhancing performance and higher directional control, increased power when exiting a turn and the ability to hold its place higher upon the wave face, reducing sideslip.

It is preferable that the board member 10 includes a directional structure or device 23, such as a vertical downward shoulder or surface or face 23 formed in the outer side portion of each of the depressions 15, 16 of the board member 10, best shown in FIG. 3, for enhancing the performance and higher directional control, increased power when exiting a turn and the ability to hold its place higher up on the face of the wave, reducing sideslip.

In operation, as shown in FIG. 4, the depressions 15 and 16 of the board member 10 control the water flow allowing high performance and control allowing the surfboard to be easily maneuvered by the user 80.

The board member 10 contains a pressure-dispersion plate 30 located within the body of the board member 10 between the upper surface 13 and the lower surface 14 and within the peripheral edge 31, slightly forward of the midpoint 32 of the board member 10.

The pressure-dispersion plate 30 acts as a load-spreading device to reduce the compression depth and construction damage to reduce compression of the board and structural damage caused by the elbows of the rider 80 thereby preventing deformation of the board and allowing it to retain its original rigidity, thickness and strength.

Accordingly, the surfboard in accordance with the present invention includes a directional control structure for allowing the surfboard to be easily maneuvered by the user to give high performance and hirer directional control while surfing.

Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
